Hi there! Regarding this issue, the PLED positive and negative polarity labels are on the back of the board. The Figure_Overall Connection Diagram only shows the front-side interfaces, which might have caused confusion. Please refer to this picture: X630-A8-Compare [1]—it should make things much clearer. Thanks for your suggestion! We’ll consider adding the back-side polarity label diagram as a reference too.
